DUMP-WAGON.

Specification of Letters Patent.

Patented J an. 22, 1907'.

Application filed May 29,1906. Serial. No. 319,250.

T0 all whom it may concern:

Be it known that I, RICHARD I-I. MACCLER NAN, a citizen of the UnitedStates, residing at the city of Philadelphia, inthe county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Dump-Wagons, of which the following is aspecification.

My invention has relation to dump-wagons, and in such connection itrelates particularly to the construction 4and arrangement of the doorsforming the movable bottom for box of the wagon and of means forengaging the doors and supporting the flaring boards of the wagon-box. y

The principal objects of my invention are, first, to shape the doors andbars secured to `the sides of the wagon-box so as to permit the doors todirectly engage the bars, and thus to dispense with the use of hingesfor such purpose; second, to provide the doors with openings throughwhich the bars are inserted to connect the same with the doors j third,to provide the doors with a flange to strengthen the same at theirpivotal ends and to receive the openings for the bars; fourth, to bendthe bars at their lower ends to form hooks so as to engage the fiangesof the doors, and, fifth, to shape the bars at their upper ends so as topermit of the support of the iaring boards of the wagon-box by the same.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, in which- Figure l is a view illustratingin side elevation a dump-wagon with thedoors in an open position andbars for supporting the doors and iiaring boards of the wagon-boxembodying main features of my said invention. Fig. 2 is across-sectional view of the dump- Wagon with the doors in a closedposition; and Fig. 3 is a detail view, enlarged, illustratingperspectively a portion of one of the doors and one of the barssupporting the same.\y y

Referring to the drawings, a represents the dump-wagon, the wagon-box bvof which is provided on the upper sides b at the upper portionthereof-with outwardly-flaring boards b2, so as to increase theload-carrying capacity of the wagon a. The bottom of the wagon-box b isformed by doors c and c', which in the present instance consists ofsheets of metal which are prevented from bending and buckling under thestress of a load resting thereon, preferably by transversely-arrangedchannel-irons d and longitudinally-arranged channel-irons e, locatedadjacent to the abutting ends of the doors c and c. The channel-irons@may be further strengthened by tubes e placed therein, which also serveto receive and guide the chain f, by means of which the doors c and care raised and supported at their abutting ends in the usual well-knownmanner.

In order to still further simplify the construction of the dump-wagon aand to dispense with the use of hinges to connect the doors c and c withthe sides t of the wagonbox l), each of the doors is provided withopenings c3, which in the present instance are arranged in right-angularextensions c2 thereof'. To the sides b of the wagon-boxb are securedbars h, preferably consisting of fiat strips of metal at their lowerends bent outward and upward to form hooks t, which by passing throughthe openings c3 of the doors c and c support the same in the manner, forexample, shown 1n Figs. 2 and 3. In addition to supporting the doors cand c the bars h also serve by means of their outwardlybent upper endsh2 to partially support and hold the fiaring boards b2 in properposition with respect to the Wagon-box b and at the same time strengthenthe sid es t thereof.

The right-angular extensions c2 of the doors c and c by forming fiangeswill strengthen the saine at the ends contiguous to the sides t of thewagon-box b.

I-Iaving thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by LettersPatent, is-

l. In a dump-wagon, a wagon-box, doors forming the bottom of said boxand having flanges provided with openings therein and flat stripssecured to the sides of said wagonbox and extending the entire widththereof, and said strips at their lower ends bent into hooks to passthrough the openings in the flanges of said doors, substantially as andfor the purposes described.

2. In a dump-wagon, a wagon-box, flaring boards forming extensions ofthe sides of said box, doors forming the bottom of said box and havingflanges provided with openings In Witness whereof I have hereunto set mytherein and flat strips secured to said Haring signature in the presenceof two subscribing boards and sides of said box and the lower Witnesses.
